Yerba Maté

ARAGORN TAKES A BREAK FROM KILLING ORCS TO DRINK SOME MATE

I am drinking mate cocido right now. That's a mate herb (yerba mate) infusion, just like tea leaves where you steep the herb in hot water and strain it to serve. I grew up on this stuff. It's excellent, with some really healthful properties (read Wiki stuff). You can drink it on an empty stomach and not have that acid you get from coffee. It doesn't give you the jitters but it does make you alert and awake. It's just great stuff. Mate is part of my waking up ritual. Upon waking, I will first eat a grapefruit and then get a huge mug of mate cocido. I don't add sugar or milk, although it's not uncommon to drink it that way. There's some Wiki info about mate below. It's sold in health food stores and some Mexican food stores around here, where I buy it in 1 kilo packages.

Update: Here's more info about yerba mate from www.yerbamate.us

Excerpt from Wiki: Drinking Mate

Mate (pronounced /'ma.te/) is a highly caffeinated infusion prepared by steeping dried leaves of yerba mate (Ilex paraguariensis) in hot water. It is the national drink in Uruguay and Argentina and a common social practice in Paraguay and parts of Chile and Brazil.

Mate is served with a metal straw from a shared hollow calabash gourd. The straw is called a bombilla, in Spanish, and a bomba, in Portuguese, and it is traditionally silver. The gourd is known as a mate or a guampa, while in Brazil it has the specific name of cuia. Even if the water comes in a very modern thermos, the infusion is traditionally drank from mates or cuias. However, "tea-bag" type infusions of mate (mate cocido) have been on the market in Argentina for many years under such trade names as "Cruz de Malta" (Maltese Cross) and in Brazil under the name "Mate Leão" (Lion Mate).

As with other brewed herbs, yerba mate leaves are dried, chopped, and ground into a powdery mixture called yerba. The bombilla acts as both a straw and a sieve. The submerged end is flared, with small holes or slots that allow the brewed liquid in, but block the chunky matter that makes up much of the mixture. A modern bombilla design uses a straight tube with holes, or spring sleeve to act as a sieve. Bombilla (IPA: /bom'biʎa/ — [bom'biʃa] or [bom'biʒa] in Argentine and Uruguayan pronunciation) usually means "light bulb" in Spanish, but locally it is "little pump" or "straw".

Excerpt from Wiki: About Yerba Mate (Mate Herb)

Yerba mate (Spanish) or erva mate (Portuguese) (Ilex paraguariensis) is a species of holly (family Aquifoliaceae) native to subtropical South America in Argentina, southern Paraguay, western Uruguay and southern Brazil. The infusion called mate is prepared by steeping the dry leaves (and twigs) in hot water rather than boiling water like black tea or coffee. It is slightly less potent than coffee and much gentler on the stomach. Drinking mate with friends from a shared hollow gourd (also called a mate in Spanish, or cabaça or cuia in Portuguese) with a metal straw (a bombilla in Spanish, bomba or canudo in Portuguese) is an extremely common social practice in Argentina, Uruguay, Paraguay, eastern Chile and southern Bolivia and Brazil. Its use has also been introduced into Lebanon and Syria, particularly among the Alawi, Druze and Ismaili minorities. It's a very popular social drink in Salamiyah, Syria.

The flavor of brewed yerba mate is strongly vegetal, herbal, and grassy, reminiscent of some varieties of green tea. Many consider the flavor to be very agreeable, however, it is generally bitter if steeped in water at boiling point and is traditionally made using boiling water combined with a little cold water. Unlike most teas, it does not become bitter and astringent when steeped for extended periods, and the leaves may be infused several times. Additionally, one can purchase flavored mate, in orange, raspberry, strong, and gentle flavorings.

Mate contains xanthines, which are alkaloids in the same family as caffeine, theophylline, and theobromine, well-known stimulants also found in coffee and chocolate. Mate also contains elements such as potassium, magnesium and manganese. Caffeine content varies between 0.3% and 1.7% of dry weight (compare this to 2.5–4.5% for tea leaves, and 1.5% for ground coffee).

Mate products are sometimes marketed as "caffeine-free" alternatives to coffee and tea, and said to have fewer negative effects. This is often based on a claim that the primary active xanthine in mate is "mateine", erroneously said to be a stereoisomer of caffeine (as it is not chemically possible for caffeine to have a stereoisomer). "Mateine" is an official synonym of caffeine in the chemical databases.

Researchers at Florida International University in Miami have found that yerba mate does contain caffeine, but some people seem to tolerate a mate drink better than coffee or tea. This is expected since mate contains different chemicals (other than caffeine) from tea or coffee.

From reports of personal experience with mate, its physiological effects are similar to (yet distinct from) more widespread caffeinated beverages like coffee, tea, or guarana drinks. Users report a mental state of wakefulness, focus and alertness reminiscent of most stimulants, but often remark on mate's unique lack of the negative effects typically created by other such compounds, such as anxiety, diarrhea, "jitteriness", and heart palpitations.

Reasons for mate's unique physiological attributes are beginning to emerge in scientific research. Studies of mate, though very limited, have shown preliminary evidence that the mate xanthine cocktail is different from other plants containing caffeine most significantly in its effects on muscle tissue, as opposed to those on the central nervous system, which are similar to those of other natural stimulants. Mate has been shown to have a relaxing effect on smooth muscle tissue, and a stimulating effect on myocardial (heart) tissue.

Mate's negative effects are anecdotally claimed to be of a lesser degree than those of coffee, though no explanation for this is offered or even credibly postulated, except for its potential as a placebo effect. Many users report that drinking yerba mate does not prevent them from being able to fall asleep, as is often the case with some more common stimulating beverages, while still enhancing their energy and ability to remain awake at will. However, the net amount of caffeine in one preparation of yerba mate is typically quite high, in large part because the repeated filling of the mate with hot water is able to extract the highly-soluble xanthines extremely effectively. It is for this reason that one mate may be shared among several people and yet produce the desired stimulating effect in all of them.

In-vivo and in-vitro studies are showing yerba mate to exhibit significant cancer-fighting activity. Researchers at the University of Illinois (2005) found yerba mate to be "rich in phenolic constituents" and to "inhibit oral cancer cell proliferation".

An August 11, 2005 United States patent application (documents #20050176777, #20030185908, and #20020054926) cites yerba mate extract as an inhibitor of MAO activity; the maximal inhibition observed in vitro was 40–50%. A monoamine oxidase inhibitor is a type of antidepressant, so there is some data to suggest that yerba mate has a calming effect in this regard.

In addition, it has been noted by the U.S. Army Center for Health Promotion and Preventive Medicine that yerba mate can cause high blood pressure when used in conjunction with other MAO inhibitor
